FRANK ZEBROWSKI, OF CLEVELAND, OHIO.

SHIP-PROTEGTOR.

Application filed July 30, 1918.

To all whom it may concern:

Be it known that I, FRANK Znnnowsxr, a citizen of Russia, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Ship-Protectors, of which the following is a specification.

The primary object of the invention is the provision of a protector for ships adapted for preventing torpedoes from injuring the ship for instance during a submarine attack, the same being also serviceable as a buffer in preventing injury to the hull by collision with docks and other vessels.

A further object of the invention is the provision of a protector for the hull of a ship, whereby missiles are prevented from injuring the hull, and which adds rather than detracts from the buoyancy of the craft, the device also serving as an adjustable outrigger assisting in stabilizing the ship.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the arrangement of parts hereinafter fully described and illustrated in the accompanying drawings, in which like reference characters designate corresponding parts throughout the several views.

In the drawings Figure 1 is a side elevation of a ship provided with my invention;

Fig. 2 is a top plan view thereof;

Fig, 3 is a vertical transverse sectional view of the same;

Fig. 1 is an enlarged detail horizontal sectional view taken upon line Iv -IV of Fig. 3; and

Fig. 5 is an enlarged elevational view of a portion of the hull protector.

My protector is adaptable for all kinds of water craft and will be hereindescribed by way of example in connection with the hull 10 of a ship having a deck 11 and cabin 12. The hull structure which is best illustrated in Figs. 3 and A of the drawings consists of inner and outer sheathings 13 and 1 1 respectively either formed of metal or wood and provided with spaced layers of cork or wood 15 between the said sheathings, While a central layer or filling 16 of cement is provided between the layers 15. Slabs or blocks 17 formed of cork are exteriorly Specification of Letters Patent.

Serial No. 247,395.

provided upon the hull l0 reaching from the deck 11 to a point 18 well beneath the water line and removed a desirable distance from the keel 19 of the ship.

' The cork slabs I? serve as buffers as well as an armor for cushioning and preventing missiles from hitting the hull 10 while the cement or concrete layer 16 entirely prevents the passing of any missile therethrough so that the inner sheathing 13 of the hull cannot be penetrated. The slab layers 17 as well as the layer 15 assist in rendering the hull buoyant and impart better floating qualities thereto.

A plate 20 is slidably positioned horizontally through the hull 10 substantially centrally thereof and provided with depending angular extensions 21 at its opposite ends for vertical positioning in the water. Cork plates 22 are provided upon the outer faces of the extensions 21 forming protectors for the central portion of the hull 10 against any oncoming missiles such as projectiles.

Helical sprmgs 23 are fixedly positioned between the extensions 21 and the layer of slabs 17 at the opposite sides of the hull 10 and whereby the plate 20 is longitudinally moved through the hull 10 when the slabs 22 of the extensions 21 are engaged by missiles at either side of the ship. The springs 23 normally space the extensions 21 at equal distances from the opposite sides of the hull 10 and bring the extensions 21 back to their normal positions whenever hit by a missile, the invention serving to cushion the missiles and leave the hull 1O uninjured.

What I claim as new is A ship hull comprising an outer metallic sheathing, an inner metallic sheathing of similar form uniformly spaced from said outer sheathing, spaced unbroken layers of resilient material of uniform thickness positioned between said sheathings, a filling layer of cement between said layers of resilient material, and exposed resilient floatable slabs surrounding and rigidly fastened to and against the outer face of said outer sheathing, said slabs reaching from the deck of the hull to a point below the waterline thereof and spaced from the keel of the same.

In testimony whereof I afiix my signature.

FRANK ZEBROWVSKI.
